Hypertension is highly prevalent and remains one of the most frequent and preventable causes of cardiovascular morbidity and mortality. Yet, suboptimal blood pressure control is common. Hypertension clinics might play an important role in improving target attainment, by targeting drug therapy adherence, improving guideline compliance and by involving pharmacists.
We aimed to characterize patient drug therapy adherence, prescriber guideline compliance and pharmacist interventions at the hypertension clinic.
A prospective observational study was performed at the hypertension clinic of a large, academic hospital. Adult Dutch-speaking patients were eligible for inclusion. Following data were collected: patient demographics, medication use, patient adherence to prescribed antihypertensive drug therapies according to the BAASIS tool and prescriber compliance to the 2018 European Society of Cardiology (ESC) hypertension guidelines.
A cohort of 108 patients was included with 51.9% male and aged 65 (IQR: 52-75) years. In total, 104 patients took at least 1 antihypertensive drug and 46 patients (44.2%) were classified as non-adherent with regard to their antihypertensive treatment; 82 patients (78.8%) had suboptimal blood pressure control. Compliance with the ESC guidelines was 66.3% prior to the consultation at the clinic and significantly increased to 77.9% thereafter (p = 0.0015). The clinical pharmacist performed a medication review for 27 patients with a total of 44 recommendations and an acceptance rate of 59.1%.
A visit to the multidisciplinary hypertension clinic improved prescriber guideline compliance and the use of single pill combinations. Involvement of a clinical pharmacist could be beneficial to further improve patient drug therapy adherence and guideline compliance.

BACKGROUND: Compliance with perioperative anticoagulation guidelines is essential to minimize bleeding and thromboembolic risks in patients undergoing surgery. Compared to vitamin-K antagonists (VKAs), perioperative management of direct oral anticoagulants (DOACs) contains fewer steps. Therefore, we hypothesized that noncompliance with guidelines in VKA users is higher than in DOAC users. The primary aim of our study was to investigate the difference in noncompliance to perioperative anticoagulant management guidelines between elderly patients using VKAs versus those using DOACs. The secondary aim was to determine the difference in occurrence of conflicting information communicated to the patients and the difference in incidence of coagulation-related adverse events.
METHODS: This retrospective non-controlled observational cohort study examined elderly patients undergoing elective orthopedic surgery in a teaching hospital in the Netherlands. All patients undergoing elective orthopedic surgery between 1 May 2016 and 1 January 2020, aged 70 years and over, using VKAs or DOACs were selected. Nonelective surgeries were excluded. The primary outcome was the noncompliance to perioperative anticoagulant management guidelines. Secondary outcomes were missing or conflicting information on anticoagulation management communicated to the patient and coagulation-related adverse events. For continuous data, the unpaired T-test was used and for categorical data, the chi-square test.
RESULTS: In patients using VKAs, noncompliance to one of the steps of perioperative anticoagulation management was 81%, compared to 55% in patients using DOACs (p < 0.001). In most cases, VKAs or DOACs were interrupted for longer than recommended. In 13% of patients using a VKA with perioperative bridging, bridging was not conducted as recommended in the guidelines. In 13% of patients using a DOAC, a low-molecular-weight heparin (LMWH) was prescribed while a DOAC had already been restarted postoperatively. VKA users received conflicting information about perioperative anticoagulation management more often than DOAC users (33% versus 20%; p < 0.001). No difference was seen in postoperative coagulation-related complications.
CONCLUSIONS: Guidelines compliance in DOAC users is higher than in VKA users. Clinical decision support to help in selecting the right interruption interval in DOAC users, simplified standardized perioperative management, good coordination of instructions given to patients, and familiarity with updated guidelines are important in reducing noncompliance.

Surgical antibiotic prophylaxis (SAP) has been proved to decrease the rate of surgical site infections (SSI), but compliance to SAP guidelines remains suboptimal.
This study evaluated the impact of periodically sending individualized feedback letters to surgeons and anesthesiologists on their compliance rate to SAP guidelines.
A total of 1491 surgeries were evaluated by retrospective chart review during the pre-intervention period and 668 surgeries were evaluated by prospective chart review during the per-intervention period. Finally, 295 letters were sent to 64 surgeons and 45 anesthesiologists. Compliance rate was assessed as an outcome composed of: indication for SAP, choice of antibiotic agent, antibiotic dose, postoperative duration, timing of the preoperative dose and intraoperative redosing. An interrupted time series design was used to assess a difference on compliance rates before and during the intervention period.
Sending individualized feedback letters to surgeons and anesthesiologists did not significantly improve the overall compliance to local SAP guidelines.
Individualized feedback letters could be part of future interventions directed at improving compliance to SAP guidelines, but are likely insufficient by themselves to provide significant results.

BACKGROUND: The emergency medical services (EMS) use guidelines to describe optimal patient care for a wide range of clinical conditions and symptoms. The intent is to guide personnel to provide patient care in line with best practice. The aim of this study is to describe adherence to such guidelines among prehospital emergency nurses (PENs) when caring for patients with chest pain.
OBJECTIVE: To describe guideline adherence among PENs when caring for patients with chest pain. To investigate whether guideline adherence is associated with patient age, sex or final diagnosis of acute myocardial infarction on hospital discharge.
METHODS: Guideline adherence in terms of patient examination and pharmaceutical treatment was analysed in a cohort of 2092 EMS missions carried out in 2018 in Region Halland, Sweden. Multivariate regression was used to describe how guideline adherence is associated with patient age, sex and diagnosis on hospital discharge.
RESULTS: Guideline adherence was high regarding examination of vital signs (93%) and electrocardiogram (ECG) registration (96%) but lower in terms of pharmaceutical treatment (ranging from 28 to 90%). Adherence was increased in cases in which the patient ended up with acute myocardial infarction (AMI) as diagnosis on discharge. Patients with AMI were given acetylsalicylic acid by PENs in 50% of cases. Women were less likely than men to receive treatment with acetylsalicylic acid and oxycodone.
CONCLUSIONS: Guideline adherence among PENs when caring for patients with chest pain is satisfactory in terms vital signs and ECG registration. Regarding pharmaceutical treatment guideline adherence is defective. Improved adherence is mainly associated with male sex in patients and a diagnosis of AMI on hospital discharge. Defective adherence excludes measures known to improve patients\' prognoses such as treatment with acetylsalicylic acid.

Newborn resuscitation guidelines recommend initial assessment of heart rate (HR) and initiation of positive pressure ventilation (PPV) within 60 s after birth in non-breathing newborns. Pulse oximeter (PO) and electrocardiogram (ECG) are suggested methods for continuous HR monitoring during resuscitation. Our aim was to evaluate compliance with guidelines and the efficacy of PO versus ECG monitoring in real-life newborn resuscitations.
In this prospective observational study, we video recorded resuscitations of newborns ≥34 weeks of gestation receiving PPV at birth.
104 resuscitations were analysed. Median (IQR) time from birth to arrival at the resuscitation bay was 48 (22-68) s (n = 62), to initial HR assessment 70 (47-118) s (n = 61), and to initiation of PPV 78 (42-118) s (n = 62). Initial HR assessment (stethoscope or palpation) and initiation of PPV were achieved within 60 s for 35% of the resuscitated newborns. Time to initial HR assessment and initiating PPV was significantly longer following vaginal deliveries than caesarean sections: 84 (70-139) versus 44 (30-66) s (p < 0.001) and 93 (73-139) versus 38 (30-66) s (p < 0.001). Time from birth and sensor application to provision of a reliable HR signal from PO versus ECG was 348 (217-524) (n = 42) versus 174 (105-277) s (n = 30) (p < 0.001) and 199 (77-352) (n = 65) versus 16 (11-22) s (n = 52) (p < 0.001).
Initial HR assessment and initiation of PPV were achieved within 60 s after birth in only 1/3 of newborn resuscitations. When applied for continuous HR monitoring, ECG was superior to PO in time to achieve reliable HR signals in real-life resuscitations.

OBJECTIVE: To validate the adherence of urologists to chemotherapy recommendations given in the EAU guidelines on PeCa. The European Association of Urology (EAU) guidelines on penile cancer (PeCa) are predominantly based on retrospective studies with low level of evidence.
METHODS: A 14-item-survey addressing general issues of PeCa treatment was developed and sent to 45 European hospitals. 557 urologists participated in the survey of which 43.5%, 19.3%, and 37.2% were in-training, certified, and in leading positions, respectively. Median response rate among participating departments was 85.7% (IQR 75-94%). Three of 14 questions addressed clinical decisions on neoadjuvant, adjuvant, and palliative chemotherapy. Survey results were analyzed by bootstrap-adjusted multivariate logistic-regression-analysis to identify predictors for chemotherapy recommendations consistent with the guidelines.
RESULTS: Neoadjuvant, adjuvant, and palliative chemotherapy was recommended according to EAU guidelines in 21%, 26%, and 48%, respectively. For neoadjuvant chemotherapy, urologists holding leading positions or performing chemotherapy were more likely to recommend guideline-consistent treatment (OR 1.85 and 1.92 with p(bootstrap) = 0.007 and 0.003, respectively). Supporting resources (i.e., guidelines, textbooks) were used by 23% of survey participants and significantly improved consistency between treatment recommendations and Guideline recommendations in all chemotherapy settings (p(bootstrap) = 0.010-0.001). Department size and university center status were no significant predictors for all three endpoints.
CONCLUSIONS: In this study, we found a very low rate of adherence to the EAU guidelines on systemic treatment for PeCa. Further investigations are needed to clarify whether this missing adherence is a consequence of limited individual knowledge level or of the low grade of guideline recommendations.

Evidence-based guidelines in HIV care aim to improve patients\' health outcomes, quality of care, and cost-effectiveness. Laboratory monitoring plays an important role in assessing clinical status of patients and forms an integral part of HIV treatment guidelines. The Dutch HIV monitoring foundation (Stichting HIV Monitoring) previously observed variation between HIV treatment centres in the Netherlands in terms of compliance with guidelines for performing laboratory tests. Drawing on qualitative research methods, this article aims to describe factors that influence guideline compliance for laboratory monitoring in outpatient HIV care in the Netherlands. Twelve semi-structured in-depth interviews were conducted with a convenience sample of physicians from four HIV treatment centres. In general, physicians perceived laboratory guidelines as useful. However, unclear online visual representation of the guidelines, a lack of set reminders for tests, and assessment of patients\' risk behaviour, which differs per patient, were identified as barriers to guideline compliance. The compartmentalisation of the Dutch healthcare system was viewed as hampering guideline compliance. A clinical-decision-support tool could possibly facilitate compliance with laboratory monitoring guidelines. Moreover, better alignment of HIV outpatient care, municipal health services and primary care, in terms of laboratory testing, could optimize efficiency, increase cost-effectiveness, and improve quality of HIV care.

Laboratory monitoring of patients using lithium is important to prevent harm and to increase effectiveness. The aim of this study is to determine compliance with the guidelines for laboratory monitoring of patients treated with lithium overall and within subgroups.
Patients having at least one lithium dispensing for 6 months or longer between January 2010 and December 2015 were identified retrospectively using data from the Dutch PHARMO Database Network. Laboratory monitoring was defined as being compliant with the Dutch Multidisciplinary Clinical Guideline Bipolar Disorders when lithium serum levels, creatinine and thyroid-stimulating hormone (TSH) had been measured at least every 6 months during lithium use.
Data were analyzed from 1583 patients with a median duration of 7- to 6-months period of lithium use. Results indicated that patients had been monitored over 6-month period for lithium serum levels 65% of the time, for creatinine 73% of the time and for TSH 54% of the time. Just over one seventh (16%) of patients had been monitored in compliance with the guidelines for all three parameters during total follow-up. Especially males, patients aged below 65 years, patients receiving prescriptions solely from general practitioners, prevalent users of lithium, patients without interacting co-medication, and patients without other days with laboratory measurements had been monitored less frequently in compliance with the guidelines.
A considerable proportion of patients had not been monitored in accordance with the guidelines. Further research is needed to understand the reasons for noncompliance and to implement strategies with the ultimate goal of optimizing safety and effectiveness for patients treated with lithium.

Sub-optimal antibiotic prescribing remains a public health concern in Namibia. The objective was to determine the level and predictors of compliance to guidelines in the prescribing of antibiotics in acute infections at a national referral hospital in Namibia to improve future prescribing.
An analytical cross-sectional survey design. The clinical records of patients receiving care were reviewed. Prescribing practices were assessed using a self- administered questionnaire with reference to Namibia Standard Treatment Guidelines (NSTG).
The majority of prescriptions (62%) complied with the NSTGs; however, lower than national targets (95%). Most prescriptions were empiric and prescribers typically made reference to the NSTG (58%). Diagnosed infections were principally respiratory infections (58%) and penicillins were the most used antibiotics. Good concurrence between signs and symptoms with the diagnosis indicated on the prescription - OR=5.2 (95% CI: 1.4, 19.2), a diagnosis of upper respiratory tract (p=0.001), oral-dental OR=0.1(95% CI: 0.03,0.3) and urogenital infections OR=0.3(95% CI: 0.1,0.95) and the prescribing of penicillins (p=0.001) or combination antibiotics and amphenicols were independent predictors of compliance to the NSTGs. The main behaviours associated with antibiotic prescribing were patient influences, clinical state, and access to guidelines.
Compliance with NSTGs is suboptimal. Prescribing of combination antibiotics, penicillins and diagnosis of oral dental, genitourinary and ear, nose and throat infections were important predictors for NSTG compliance. There is a need to implement antibiotic indicators and stewardship programmes, and ensure access to NSTGs, to improve future antibiotic prescribing in Namibia.
