Professional discipline and regulatory law

Regulatory charges against a hospital’s Director of Nursing in the aftermath of the death by overdose of a consultant anesthetist within the hospital. Although wide ranging, the gravamen of the charges turned on the Registrant’s alleged failure to ensure that controlled drug processes within the hospital were safe. The case involved a large volume of disclosure and necessitated the assimilation of large amounts of material pertaining to hospital processes, chains of responsibility and corporate structures. Finding of no impairment.

Dentist facing regulatory proceedings following a conviction for causing death by careless driving.

Dentist alleged to have made off with payments from a patient, having extracted a number of teeth and having failed to undertake the reconstructive implant surgery promised, together with having allegedly taken payments to a personal card machine when they should have been made to the surgery employing him.

5 week case involving wide ranging allegations including allegation of dishonesty against clinical lead and deputy head teacher at a school for children with profound physical and mental impairments.

Case running for several weeks, involving a care home manager and former CQC inspector facing wide ranging allegations of neglect, elder abuse and poor treatment of relatives. Case marked by the challenging nature of the complainant family, who had brought similar complaints about the registrant to around twenty separate organisations.

K (a nurse)
Health case involving background of alcohol misuse and severe depression, including episodes of overdose. The Registrant had taken considerable amounts of sickness absence, against a background of both domestic abuse and bullying in the workplace. Not found impaired.

R. Mather
Allegations of dishonesty around the lack treatment of a pressure ulcer on the stump of an amputee. Various further allegations relating to the poor episode of care, shortly after qualification. Dishonesty found not proved, no impairment found.

The Registrant had repeatedly failed to declare having a recent diagnosis of tuberculosis together with current undiagnosed lung infection upon applying for work as a nurse within a prison. The registrant had admitted not having disclosed this due to a fear that, in doing so he would not have been offered the job. Avoided findings of dishonesty and of impairment.

Appeal against refusal to readmit accountant further to disqualification as a director. The ICAEW ultimately conceded that the panel at first instance had made material errors of fact in such a way as distorted the proceedings against the appellant and deprived him of the opportunity properly to present his case or to evidence the process of remediation that he had undergone or his level of insight.

A nurse having been referred to the NMC following the tragic death of a young lady from sepsis. The registrant had seen the deceased in an outpatients clinic, had failed to recognise the symptoms of sepsis and had directed her to a GP's surgery rather than as an urgent referral to A&E. It became clear in the substantive hearing that there had been institutional failings across multiple NHS service providers and that the registrant's failings did not amount to misconduct.

A social worker facing misconduct proceedings before the HCPC in connection with an allegation of an improper relationship with a service user. It became clear during the course of proceedings that the registrant had in fact been the victim of serious psychological, physical and financial abuse at the hands of the service user, who, as well as having been in a position of some vulnerability, was also deeply entrenched within serious criminality.
