RESUMEN

Background: South Africa has high tobacco-attributable mortality and a smoking prevalence of 32.5% in males and 25.6% in females. There are limited data on smoking prevalence and desire to quit in hospitalised patients, who have limited access to smoking cessation services. Objectives: To determine smoking prevalence and the extent of nicotine withdrawal symptoms, using a hospital-wide inpatient survey. Methods: A 1-day point prevalence survey was conducted at Groote Schuur Hospital, Cape Town. All wards except the haematology isolation, active labour and psychiatry lock-up wards were evaluated. Smoking status, withdrawal symptoms and desire to quit were established. Results: Smoking status was confirmed in 85.8% of inpatients (n=501/584), of whom 31.9% (n=160) were current smokers; 43.5% (n=101/232) of male and 21.9% (n=59/269) of female inpatients were smokers. Documentation and confirmation of smoking status was highest in the maternity wards (100%) and lowest in the surgical wards (79.6%) and intensive care units (70.0%). Smoking prevalence ranged from 47.6% in male surgical patients to 15.2% in maternity patients. Of the smokers, 54.5% reported being motivated to quit, with a median (interquartile range) Fagerström test for nicotine dependence score of 4 (2 - 6), and 31.4% reported moderate to severe cravings to smoke, highest in the surgical wards. Conclusion: Smoking prevalence was higher in hospitalised patients than in the local general population. Many inpatients were not interested in quitting; however, a third had significant nicotine withdrawal symptoms. All inpatients who are active smokers should be identified and given universal brief smoking cessation advice. Patients with severe withdrawal symptoms should be allowed to smoke outside, and nicotine withdrawal pharmacotherapy should be provided to those who are bedbound or express a desire to stop smoking during the current admission. Study synopsis: What the study adds. A single data point prevalence study of active smokers at Groote Schuur Hospital, Cape Town, was conducted. The prevalence of smoking was higher in the hospitalised patients than in the general community, but not all smokers were identified by the clinicians. Although symptoms of nicotine withdrawal were severe in some patients, motivation to quit smoking was not related to the degree of withdrawal being experienced. Many patients were not motivated to quit smoking.Implications of the findings. Better identification of inpatient smokers is required, and all should be given smoking cessation advice. Withdrawal symptoms can be severe in some patients, and those who are not interested in stopping smoking should allowed to smoke outside or be provided with nicotine withdrawal pharmacotherapy while in hospital. Those who are willing to quit should be supported as well as possible, including provision of nicotine replacement therapy or varenicline, and followed up after discharge as best practice.

RESUMEN

BACKGROUND: Up to a quarter of inpatients in high-income countries (HICs) self-report beta-lactam allergy (BLA), which if incorrect,increases the use of alternative antibiotics, worsening individual health outcomes and driving bacterial resistance. In HICs, up to 95% ofself-reported BLAs are incorrect. The epidemiology of BLA in low- and middle-income African countries is unknown. OBJECTIVES: To describe the epidemiology and de-labelling outcomes of self-reported BLA in hospitalised South African (SA) patients. METHODS: Point-prevalence surveys were conducted at seven hospitals (adult, paediatric, government and privately funded, district andtertiary level) in Cape Town, SA, between April 2019 and June 2021. Ward prescription records and in-person interviews were conductedto identify and risk-stratify BLA patients using the validated PEN-FAST tool. De-labelling was attempted at the tertiary allergy clinic atGroote Schuur Hospital. RESULTS: A total of 1 486 hospital inpatients were surveyed (1 166 adults and 320 children). Only 48 patients (3.2%) self-reported a BLA,with a higher rate in private than in government-funded hospitals (6.3% v. 2.8%; p=0.014). Using the PEN-FAST tool, only 10.4% (n=5/48)of self-reported BLA patients were classified as high risk for true penicillin hypersensitivity. Antibiotics were prescribed to 70.8% (n=34/48)of self-reported BLA patients, with 64.7% (n=22/34) receiving a beta-lactam. Despite three attempts to contact patients for de-labelling atthe allergy clinic, only 3/36 underwent in vivo testing, with no positive results, and 1 patient proceeded to a negative oral challenge. CONCLUSION: Unlike HICs, self-reported BLA is low among inpatients in SA. The majority of those who self-reported BLA were low risk fortype 1 hypersensitivity, but outpatient de-labelling efforts were largely unsuccessful.
